Been a Ford guy my whole life and have converted to the Chevy crowd, so this is new to me. My floater has a 1972 BBC with iron heads. I am in the porcess of switching to Victor Jr type intake and I ordered the correct intake gaskets Fel-Pro 1212. When I opened the package last night I came with 4 tin squares for plugging or restricting the exhaust crossover. The instructions are not clear to me. Do I need these squares installed with this manifold? If so 2 on both sides? Or is that only used if the manifold had an EGR? I read that I should install because it will blow out the gasket from heat and on another thread said dont because the tin will damage the aluminum intake.

The tin squares are for the heat crossover. An Eddy Victor Jr manifold doesn't have a heat crossover, so the squares are not needed. A "Victor jr type" (what I read: single plane manifold of unknown manufacturer) May have a crossover, then use the solid squares to block off the crossover passage, unless you run an old school manifold heat riser choke.

Def no crossover, its the victor jr single plane knock off. Ok then tonight I will just install without the tin squares. Thanks.
